LG LED 42LE5300. We just bought this TV last week. When we first installed it, we noticed uniform horizontal tiny lines on the picture. We tried to change the cable box, use high res. HDMI, even tried playing blue ray disc on it, but still had the lines. We were going to return it, but one evening, we turned it on, & it was clear, w/ no lines. We thought that was it, a few days later, the lines are back. What can we do to fix it? Or do we just need to replace the TV? We're very disappoint

I have a SANYO DP46848, 46 inch flat screen hdtv purchased about 2 - 3 years ago. The screen goes dark on the left side (top .25% is ok). It sometimes fixes itself after an hour or so. Sometimes you can fix it by placing your hand on the dark spot for 10-15 seconds. There is a thin horizontal line about 1/4th of the way down from the top with the top of line ok when the bottom of line area goes dark. LCD Controller? or Main Board? or Power Supply or the Panel itself? I have a picture if that
